Answer:
542
Step-by-step explanation:
So X is the number of finals graded by teacher last year
she graded 83 more finals than the last year
and the total number of finals she graded this year is 625 so we have an equation
X + 83 = 625
and as you solve it for X
X = 625-83
x = 542
Solve for v by simplifying both sides of the equation, then isolating the variable.

I believe it would be this:
3 (2×-5)=1+4× 6-15=1+4× 6×=1+4×+15
I hope this answer helped, and my deepest apologies if I have calculated wrongly. Math is tricky! :)
